Okay,
I've looked EVERYWHERE and everyone keeps answering this question like we're going to actually "download" a file actively.
I am not downloading a file. I am not Uploading a file. I just want a dialog that allows the user to easily provide the path and filename for entry into a textbox so they don't have to type the whole damn thing manually.
don't ask why, or what I'm using it for, I just want to know how to open a simple filesystem dialog. The user browses, types a file name, clicks save, and the text input on the form is populated with the fully qualified path.
This is definitely possible (maybe not with javascript, but I've seen countless pages that open up a file browse dialog) so how do I do this?
Thanks

Not too long ago browsers disabled showing the full path to the file on your local machine due to security reasons.
Otherwise you could write ajax script to submit client's paths to the server without the person knowing.
Check the sample script:
$('#fileSelector').on('change', function( e ) {
$('#value').text( e.target.value );
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="fileSelector" type="file" />
<div id="value"></div>
You can do this with jQuery:
$(":file").change(function(){
alert($(":file").val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="file">
</form>

I am learning javascript. Can I use javascript to change the browse file path when input type is file?
<input type="file" id="file_input" name="file_name"/>
When I click the "browse file..." button, the window is my assign path.
I do not hope the user to find the file location from the window. I am sorry my poor English
I don't think this is possible. See here for a more complete explanation, but basically it's a security issue. Code from your web page should not be allowed to know anything about the file structure on a client machine.
When uploading a file, before pressing the upload button, the folder/file path is visible in the website's upload form.
.
Is the website able to record that data?
Normally a website could possibly record any data typed into a web form - is this any different?
It doesn't appear to work. I created the following fiddle https://jsfiddle.net/5samkn5a/
Basically I took an input
<input type="file" id="input"/>
And set a listener to its value
$(function(){
$("#input").change(function(){
console.log($(this).val());
})
})
Then I tried it in the latest chrome/firefox/edge
They all give a fake path as value. The only thing that's real is the file name. May be that some browsers actually expose the full path, but not the ones I tested.
It makes sense that the browser is shielding this information since at least on windows when you are choosing a document it will most likely reside in your current user directory. So the path will contain your local user name and that's not something you want to give to a random website, right?
I know that since the creation of HTML5 there has been many additions that make programming websites more easy than ever. It seems they may have failed to add a File system that actually creates a file in a specified directory (not to my knowledge anyway). I have been searching the web and have found nothing about doing such a thing without using a 3rd party i.e JQuery, php, Javascript Libraries. I assume that since there is pure js libraries that can accomplish this that it is possible, but I do not know for sure. What I would like to do is output an html file from the outerHtml generated in my JavaScript minus the script source itself. Note that I do not want the client to have to download.
Try this:
<head>
<script type="text/javascript">
function WriteToFile(passForm) {
set fso = CreateObject("Scripting.FileSystemObject");
set s = fso.CreateTextFile("C:\test.txt", True);
s.writeline("HI");
s.writeline("Bye");
s.writeline("-----------------------------");
s.Close();
}
</script>
</head>
<body>
<p>Fill out the form below:
</p>
<form onSubmit="WriteToFile(this)">
Type your first name:
<input type="text" name="FirstName" size="20">
<br>Type your last name:
<input type="text" name="LastName" size="20">
<br>
<input type="submit" value="submit">
</form>
This will work only on IE.

Preventing webpage scripts from creating files on local filesystem is done for your own security. You don't want website you visit create an executable file on your local disk with virus.
There is a File System API in HTML5, but it's kind of internal filesystem intended as a local storage for user data.
You can force user to save file by returning HTTP header Content-Disposition with value attachment; filename=example.csv. This will force browser to save file locally.
I am trying to allow users to upload pictures to the server.
I am trying to create a similar system to any website that has an 'attach' file or 'upload image' feature. All I need is to get the full path of the file select by the file dialog.
I tried using this for the file dialog with no success:
<input type="file">
This method does not provide the full file path, due to security reasons. My question is how can I create a similar input dialog to websites like tinypic, photobucket, etc.. that can help users input the full file path of a given image, into an input field?
I am aware that this cannot be done using the method above for security reasons, however, I have seen this done before on various websites without any problems, I was wondering what I had to do to implement a similar file dialog that helps fill in the text, which is a full file path, of an input field?
It is not possible to get the file full path on local machine using browser and javascript.
However, as you would like to upload the file to the server, the easy possibility I see is to use html form with input type file. You will receive the file on your http server when the form is submitted.
Here is a very good url http://www.cs.tut.fi/~jkorpela/forms/file.html that explains the whole process nicely.
I've a very small doubt. I've a html tag to browse the file. and as soon as I browse the file from the local server, I want to set that path to the source of image tag. Is it possible to implement?
I've code something like this.
<form name="image" id="image" enctype="multipart/form-data" action="" method="post">
<input type="file" name="img" />
<img src=""></img>
</file>
So as soon as I browse and select the file from the local server,that path should be set to image tag.My intention is to browse the image and display it in that page itself. Any help will be appreciated. Thanks in advance.
Browsers have now allowed you to access the path of a file from the input[type=file] tag for a long time. You can't simply do it like you're trying to. In order to accomplish your goal of showing the file after the user selects it, you actually need to upload it to your server. This typically requires a page-refresh, but there are plenty of javascript libraries that are available in order to make it happen without refreshing the page. Once the file is uploaded, you can "ping back" a URL to view the image, and load that in your image tag.
The jQuery library I've been using recently to do inline file uploads is jQuery File Upload
What you need is the full path to the file on the client side - which is not allowed (see also this thread).
Sorry mate, but without sending the file to the server you can't do anything with it other than getting the file name (not the path), the file type and the file size.
